XmlNode.RemoveAll Method

Removes all the child nodes and/or attributes of the current node.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public virtual void RemoveAll()

If a removed attribute is known to have a default value, an attribute immediately appears containing the default value and, if applicable, the corresponding namespace URI, local name, and prefix.

This method is a Microsoft extension to the Document Object Model (DOM).

Notes to Inheritors

When overriding RemoveAll in a derived class, in order for events to be raised correctly, you must call the RemoveAll method of the base class.

The following example removes all child and attribute nodes from the root node.


using System;
using System.IO;
using System.Xml;

public class Sample {

  public static void Main() {

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");

    XmlNode root = doc.DocumentElement;

    //Remove all attribute and child nodes.
    root.RemoveAll();

    Console.WriteLine("Display the modified XML...");
    doc.Save(Console.Out);

  }
}
